Abstract
The Adelaide Gay Community Periodic Survey is a cross-sectional survey of gay and homosexually active men recruited through a range of gay community sites in Adelaide. The project was funded by the Department of Human Services, South Australia. The Periodic Survey provides a snapshot of sexual and HIV-related practices among gay and homosexually active men. The second survey was conducted in November 1999 and these data can be compared with those obtained from the initial survey conducted in November 1998.
